The present invention relates to an artificial nail for application to a human natural nail, in particular to a method and a device for producing and fixing artificial nails on human natural nails for cosmetic and aesthetic purposes and for protecting the nerves in the tips of the fingers and toes. this flexible so-called tip can be easily adapted to the given shape of the natural nail.

Such a preparation for coating fingernails or toenails and a corresponding method are known in the prior art from EP 0 954 230 B1. Here is a method for applying artificial fingernails using a so-called nail packaging with a fibrous tissue and an effective amount of a

Polymerization catalyst embedded in a tissue disclosed.

Template Modeling and Tip & Overlay. In Europe, the Tip & Overlay technique is the most common

spreads as the templates modeling requires a certain know-how, and not all materials can be worked on template.

Another disadvantage in the prior art is that the conventional artificial nails available on the market require great dexterity and knowledge of processing.

Fig. 1 shows a schematic side view of the tip of a human finger 2 of the hand or toes 2 'of the foot. Between the natural nail 3 and the artificial nail 4, an adhesive layer 5 to be applied is arranged, which supports the artificial nail 4 on a part of the natural nail 3

attached. For this purpose, the adhesive layer is thinly applied to the surface of the natural nail 3 and briefly exposed, for example in the device 1, a radiation which gives the adhesive a medium to strong viscosity, whereby the adhesiveness of the adhesive is influenced so that the Although artificial nail 4 adheres, but is not yet completely fixed in its final position, so that the artificial nail can still be moved to be brought into its final position, which makes the overall picture of the hand most beneficial. The artificial nail 4 is made of a wafer-thin fiberglass synthetic resin material of thickness (d) of about 0.1-0.4 mm, preferably about 0.1 mm to about 0.2 mm, resulting in that The artificial nail 4 can be easily aftertreated by cutting tools and files. In one embodiment, the artificial nail 4 is slightly convex on the surface and the ends extend in a rounded tip 6, 6 '. Basically, two embodiments of the artificial fingernail according to the invention are provided, wherein an embodiment is longitudinally and transversely arched and a further embodiment is curved transversely to the longitudinal axis C-shaped. In this case, in both embodiments, the ends 19, 19 'are straight or formed, either arcuately inward or outward, or a mixture of both, one side in and the other side out, depending on the application (s.

Device 10 is composed of a first molded part 11, which has at least one concave recess 12. The surface of the first molding 11, together with the concave recess 12, is first formed with a bonding-immune, permanent, non-separable layer 13, e.g. Teflon, to prevent the forming matrix 14 of fiberglass material and a suitable light or white synthetic resin with the surface of the first molding 11 connects and thereby no smooth surfaces of the

artificial nail can arise. Over the layer 13, a further layer 14 of fiberglass material is arranged during production, which forms part of the artificial nail 4 to be produced in the subsequent method steps. The fiberglass material 14, whose specific

Weight between 15 - 30 g / m² is preferred, is soaked before processing or deformation with a special resin, which ultimately u.a. causes the machined and cured fiberglass material to be transparent in the

molded state is formed. Between the layer 14 and a second mold part 16 with at least one convex curvature 17, is a relatively thick yielding

Material 15, eg silicone, is arranged to evenly distribute the pressure (p) exerted by the punch 16 on the fiberglass material. The punch 16 is therefore first moved onto the layer 15, which transfers the pressure (p) only delayed to the matrix 14 made of fiberglass and synthetic resin. The thickness of the layer 15 is between 3 and 30 mm, wherein the material z. B. is a suitable silicone. The actual manufacturing process, that is, in particular the deformation of the fiberglass matrix 14 is carried out either under vacuum or in a liquid, such as synthetic resin, including the individual components are housed in a housing 18, which among other things, the better distribution of the special resin is used. The deformation process lasts between 1 to 8

Minutes, which depends on the material used. In the molding of the fiberglass matrix 14 in a resin bath eliminates the spraying of the fiberglass braid with resin and is replaced by soaking the

Fiberglass material in clear resin bath. Otherwise, the deformation process is similar to before. Following the deformation of the matrix 14, it becomes radiation for a period of 30 seconds to 5 minutes

predetermined wavelength (λ) or other field, e.g. exposed to a temperature field, which causes curing of the layers or matrix 14, wherein the field i.d.R. is a □ V radiation. Following the curing of the molded artificial nail 4, the first molding 11 is fed to a punch punching out of the composite of the matrix of fiberglass material and synthetic resin at least one artificial nail 4, the lengths and widths of the artificial nails being variably adjustable and selectable are.

In another method of cutting out the artificial fingernail tip 4, the deformed matrix 14 becomes one

Embodiment. The curvature of the finished artificial nail 4 may also be different at different points of the artificial nail 4, z. B., the curvature in the region of the edges 19, 19 'or in the middle 20 may be more pronounced than on the remaining surface of the

artificial nail 4. In the simplest embodiment, the curvature depends on the radius of curvature (r) of each finger or toe of the human body

can be different. The radius normally varies between 5 mm and 10 mm (5 mm <r <10 mm) and lies

preferably at 7 mm, while the midpoint angle () is between 30 ° and 130 ° (30 ° <a <130 °), preferably between about 50 ° and 100 °. The thickness (d) of the artificial nail 4 is substantially the same in all places, so that no different biases in processing the

artificial nail occur. In practice, the

Sheet dimensions are determined so that the edges 19, 19 'come in the area of the nail bed of the natural nail when pressing down the artificial nail.

FIGS. 5a to 5c show the schematic plan view of three exemplary embodiments of the artificial nail 4, in which the edges 19, 19 'are arranged parallel to one another. In other embodiments, the edges 19, 19 'are arranged at a predetermined angle to each other, which depends on the intended use, ie the individual shape of the natural nail 3. In Fig. 5a, the two ends 22 of the artificial nail 4 are straight, the ends in Fig. 5b once straight and once bent and Fig. 5c once convex and concave once.
